Three people were jailed for the attack on Nattalie Muir in Whitburn, which saw her left in the street to die.

Since it began, NKBL has recruited 130 "peer educators" who discuss the dangers of knife carrying with young people and identify positive alternatives to violence.

Councils, police and youth groups are also involved in delivering the message to schools and communities.

Justice Secretary Kenny MacAskill said: "Since No Knives, Better Lives started in 2009, it has aimed to challenge attitudes to carrying knives and to work with young people to find alternatives to violence and make good decisions about their lives.

"There is no doubt that Scotland is a safer place than it was even a few years ago, with recorded crimes of handling an offensive weapon at their lowest level in 27 years, falling by 60% since 2006/07, and violent crime at a 38-year low.

"Education and prevention is fundamental to tackling the root causes of violence and crime. That's why the Scottish Government has provided more than £2 million of funding to No Knives, Better Lives in the past five years, and why we are committed to rolling out the programme across Scotland."

NKBL has previously operated in Clackmannanshire, East Ayrshire, Edinburgh, Glasgow, Inverclyde, North Ayrshire, North Lanarkshire, Renfrewshire, South Lanarkshire, West Dunbartonshire and West Lothian.

YouthLink Scotland chief executive Jim Sweeney said: "The success of No Knives, Better Lives is a powerful example of the positive impact that youth work can have in helping young people deal with difficult situations and make good decisions.

"We will continue supporting the campaign as it is rolled out across Scotland, working in partnership with the Scottish Government and local authorities."
